SCALE-PAN SUPPORT.

Specification of Letters Patent.

Patented sept. 9, 191s.

Application led October 12, 1910. Serial No. 586,807.

To all whom t may concern Be it known that we, PETER KEIL and ERNEST A.STEPHENS, both citizens of the United States, residing at Elkhart, inthe county of Elkhart andv State of Indiana, have invented certain newand useful Improvements in Scale -Pan Supports, of which the followingis a specification.

This invention relates to scale pan supports and has for its primaryobject to provide a new construction, combination and arrangement ofparts in a device of this nature. Y

Une of the objects of this invention is to provide improved means formaintaining the scale pan in an upright position.

Another object is to provide an improved combination and arrangement ofparts inv the supporting and guiding links whereby the scale pan issupported in upright position on a pivotally mounted scale beam.

Anotherobj ect is to provide an improved connection between the guidelinks and the scale pan support. i

Another object is to provide improved means for mounting the guide linksupon the base of the scale.

Other and further objects will appear in the specification and bespecifically pointed out in the appendedclaims, reference being had tothe accompanying drawings exemplifying the invention, and in which-Figure 1 is a longitudinal section of a portion of a scale provided withour improvements, parts being shown in elevation. Fig. 2 is a detailelevation of portions of some of the links, parts being broken away toshow the interior construction of one of the links. Fig. 3 is a sectionon the line IIL-III, Fig. 2.

Referring more specifically to the eXemplification of the inventionshown in the drawings, a base member 1 provi-ded with a verticallyprojecting pedestal or stand 2 is provided with a top plate 3. Rigidlysupported on the top plate 3 in any suitable manner is a supportingbracket 4 provided with bracket arms 5 upon which is pivotally mountedat 6 a scale beam 7, said scale beam being provided in the usual mannerwith a poise scale bar 8 indicated in dotted lines in Fig. 1 upon whichslides a poise weight 9. Swingingly mounted upon the scale beam 7 in anyusual or well known manner, is a scale pan support comprising a crossbar 10 with depending arms 11 which are usually mounted on knife edgescarried by the scale beam 7 by means of agate bearings. Projectingthrough the cover plate 3 and seated in a socket in the base of thesupporting bracket 4, is a post 12 which is held in position by means ofa stud screw 13 which passes through a perforation in the bracketsupport 4 and threads into a threaded hole within the upper end of thepost 12. vAdjustably connected with the scale pan support 10 preferablyby being slidably mounted in a circular hole formed in the dependingportion 14 of the scale pan support, is a rod or member 15 which is heldin its adjusted position by means of a set screw 16 threaded within thepart 14 and engaging the upper end of the rod 15. In order to provide anadjustable abutment for the rod 15, a grub screw 16 is threaded in thepart 14 and projects through from the upper face of said part 14 intothe socket for the rod 15. Said grub screw or abutment 16 may thereforebe moved backwardly and forwardly to limit the upward movement of therod 15. A lock nut 17 serves to lock the grub screw 16 in any desiredposition. Connecting the lower ends of the depending post 12 and the rod15 in such a manner as to maintain the rod 15 in an upright position forany position to which the scale beam may be swung, is a connecting link1S which is pivotally connected at its ends with the post 12 and rod 15respectively in the manner now to be pointedl out.` Referring now toFigs. 2 and 3, the lower ends of said post 12 and rod 15 are reduced insize at 19 and 20 respectively for the reception of bearing brackets 21,22, said bearing brackets being provided with flanges projecting onopposite sides of the reduced portions 19 and 20 and secured thereto bymeans of bolts or rivets 21. As shown in Fig. 3, each of the bearingbrackets is provided with a pair of depending arms 24 within which abearing pin 25 is rigidly secured by a nut 26. Said bearing pin isprovided adjacent its center with a reduced neck portion 27 whichprovides a race for a plurality of ball bearings 28 which are mountedbetween said reduced neck 27 and the cylindrical wall of a hole providedin a link 29. On opposite sides of the links 29 are a pair of link bands30 which are rigidly locked to the link 29 by means of suitablefastenings such as screws 31 held in position by nuts 82. The bands oi'straps 30 are provided With perforations fitting the larger portions ofthe bearing pin 25 about which they lit snugly to inclose :the

balls 28.

What We claim isconnected at its ends With said post and depending rodrespectively, and an adjustableE n is adapted to lit over the ballsaround said abutment for said depending rod.

2. ln a scale, the combination With a 'base member, of apost dependingtherefrom, a"

scale Jbeam pivotally mounted on said base member, a scale pan supportpivotally mounted lon said scale beam, a dependingy rod adjustablyconnected to said scale ,panI support, means for rigidly locking saidrod n u "being provided at 'their lower ends With rein any position towhichV it may be adjusted, I

Aduced portions, a bearing Ebracket mounted an abut-ment for said rod,said abutment beingl adjustably mounted in said scale pan,

support, means for locking said abutment in any adj-usted position, anda link pivotally connected at its ends to said depending post and rodrespectively.

3. ln a scale, the combination of a basel member provided With a hollowupright stand, said stand being' provided With a perg fora ted coverplate,

a post 'ext-ending through the perforation in said cover pla-tof? anddepending "therefrom, a bracket support mounted on said cover plate andprovided with' a hole into which the end of the post projects, meansprojecting through saidfl bracket support and engaging said Ypost foi"maintaining it in position, a scale beam; pivotally vmounted on saidbracket siipport a scale pan support pivotally mounted on,

said scale beam and vprovided Witha depending rod, and a link pivotallyconnected at its ends With said .post and rod respectively.

1l.. In a scale, the combination With a base member, of a scale beampivotally mounted thereon, a scale pan support pivotally mounted on saidscale beam and provided With a ydepending rod, a post depending fromsaid base member, said post and rod being provided at `their lower endsWith reduced portions, a bearing bracket mounted on each reducedportion, a bearing pin iin each bearing bracket, said bearing' pinsbeing provided with -ball 'bea-ring Araces formed therein, and a linkprovided at' each end with a cir-cular aperture whereby said link pins.

o. In a scale, -tlie combination with a base member, of a scalebeampivot-ally mounted thereon, a scale pan support pivotal-ly.

mounted on said scale beam and provided with a depending rod, a Vpostdepending from said base member, said post androdon each reducedportion, a bea-ring pin in each bearing bracket, said bearing pins beingprovided with ball bea-ring races formed therein, bearing balls, -avlink provided at each 'end with a circular aperture whereby said linkis adapt-ed lto lit over the balls around said pins, and a pair ofstraps on opposite sides-of said link, said straps being rigidly securedto said link.

In testimony whereof We have sig-ned our naines to `this specification,in the presence of tivo subscribing Witnesses, on this :24th day ofSeptember, A. D. 1910.
